The values of the specific energy consumption and the melting performance calculated from laboratory measurements of soda-lime-silica glass predict efficient sand dissolution and bubble removal under conditions of rapid melting kinetics and high utilization of the melting space. The impact of glass flow character on bubble removal was investigated in the continuous horizontal or vertical melting channel. The results gave a chance to control the fining performance of the channel by proper temperature boundary conditions. The model of the bubble behavior under effect of both gravitational and centrifugal force has been established in the rotating discontinuous cylinder. The separation of bubbles by centrifuging was influenced by bubble contraction and by partial or complete dissolution in the melt; optimum conditions of the process, applicable in practice, lie in the region of relatively low rotation velocities. Sulfur compounds as chemical accelerator of glass melting were investigated from the point of view of several processes: sand dissolution, fining, bubble nucleation and melt foaming. The experimental work attempts to present the picture of glass melting with sulfur compounds in its complexity. The presented subjects are intended to contribute to advanced glass melting process.
